Let me just jump in real quick and provide some info without supporting any side. You’re referring to the authoritarian communism, and yes, none of it worked, and again yes, it’s the only one that really happened in our history.

What you’re missing is that the other person is referring to the lower left quadrant of the political compass, or libertarian socialist quadrant. And no, libertarian is referring here to the lack of or very week and non focused (with a lot of people in it) government.

For a great breakdown of the political compass I recommend Wendigoon’s video on the topic. That’s all I’m gonna say here, have a pleasant day and a good watch if you do decide to click on that link.
